英文:
Keyboard automatically closes in flutter while using form
问题
在我的代码中，当使用text formfield时，我的键盘会自动关闭，我发现当我使用Form和它的验证键时，键盘会关闭，我正在使用带有表单的列表视图，但当我删除表单时，它可以正常工作，但我需要一个表单来验证，我该怎么办？
Form(
key: _formKeyPlant,
child: ListView(children: [
SizedBox(
width: size.width,
child: Column(
children: [
CustomTextField(
controller: name,
title: 'Name',
validator: (text) {
if (text == null || text.isEmpty) {
return 'Required';
} else if (text.contains(RegExp(r'[0-9]')) ||
text.contains(RegExp(r'[#?!@$%^&*-]'))) {
return 'Invalid Input';
}
return null;
},
),
15.verticalSpace,
CustomTextField(
controller: location,
title: 'Location',
validator: (text) {
if (text == null || text.isEmpty) {
return 'Required';
} else if (text.contains(RegExp(r'[0-9]')) ||
text.contains(RegExp(r'[#?!@$%^&*-]'))) {
return 'Invalid Input';
}
return null;
},
),
15.verticalSpace,
CustomTextField(
enabled: false,
onTap: () async {
final response = await showAppBottomSheet(
context,
const TreesInfoBottomSheet(),
);
if (response != null) {
treeType.text = response['name'];
treeTypeId = response['id'];
}
},
controller: treeType,
title: 'Tree Type',
),
15.verticalSpace,
CustomTextField(
controller: ageOfTree,
inputType: TextInputType.number,
validator: (text) {
if (text == null || text.isEmpty) {
return 'Required';
} else if (text.contains(RegExp(r'[a-z]')) ||
text.contains(RegExp(r'[A-Z]')) ||
text.contains(RegExp(r'[#?!@$%^&*-]'))) {
return 'Invalid Input';
}
return null;
},
title: 'Age of Tree',
),
15.verticalSpace,
CustomTextField(
controller: registration,
title: 'Registration ID (Optional)',
),
15.verticalSpace,
CustomTextField(
maxLines: 6,
controller: comments,
labelText: 'comments',
),
40.verticalSpace,
],
).px(18),
),
]),
),

以下是您要的翻译内容：
使用表单和滚动小部件正确的格式如下，以确保在文本字段上键盘永不隐藏：
final Key _key = GlobalKey();
FocusNode f1 = FocusNode();
FocusNode f2 = FocusNode();
@override
Widget build(BuildContext context) {
return Form(
key: _key,
child: SingleChildScrollView(
child: Column(
children: [
TextFormField(
focusNode: f1,
onFieldSubmitted: (c) {
f1.unfocus();
f2.requestFocus();
},
),
TextFormField(
focusNode: f2,
),
],
),
),
);
}
英文:
Correct formate of using textform filed with form and scroll widget is
> Please try the below code your keyboard with never hide on textformfiled
final Key _key = GlobalKey();
FocusNode f1 = FocusNode();
FocusNode f2 = FocusNode();
@override
Widget build(BuildContext context) {
return Form(
key: _key,
child: SingleChildScrollView(
child: Column(
children: [
TextFormField(
focusNode: f1,
onFieldSubmitted: (c) {
f1.unfocus();
f2.requestFocus();
},
),
TextFormField(
focusNode: f2,
),
],
),
),
);
}
